4 Axis SCARA Robot
RL Robotics 4-Axis SCARA Robots provide a combination of high-speed motion, positioning accuracy, repeatability and compact mechanical design for industrial automation. Available in 4 kg to 10 kg payload configurations, the series is suitable for applications ranging from lightweight component handling to higher-payload material transfer.
The four-axis configuration enables fast and controlled X-Y positioning, Z-axis vertical movement and rotational orientation, making the robot particularly effective for repetitive point-to-point operations. Its compact footprint allows efficient integration into production cells where workspace and cycle time are critical factors.
RL Robotics SCARA robots systems can be configured with application-specific grippers, feeders, conveyors, sensors, vision systems and peripheral equipment to automate complete workstations.
SCARA robots are suitable for Pick & Place, Assembly, Machine Tending, Sorting, Packaging, Dispensing and Material Handling applications.

What is a 4-axis SCARA robot used for?
RL Robotics’ SCARA series is built for high-speed, single-plane work — pick & place, assembly, machine tending, sorting, packaging, dispensing, and material handling. The 4-axis design (X-Y positioning, Z-axis vertical stroke, and rotational orientation) makes it ideal for repetitive point-to-point cycles where speed and footprint matter more than 6-axis flexibility.
What payload options are available for Scara robots?
The SCARA Robots series spans 4 kg to 10 kg maximum payload across 7 models — from the compact SAA4-0/0.40 (2kg rated / 4kg max) up to the SA10A-10/0.80 (5kg rated / 10kg max). Rated payload is roughly half the max across the lineup, so match your part weight plus end-of-arm tooling to the rated figure, not max.
How accurate are RL Robotics SCARA robots?
Yes. The Q Series is specifically designed for painting applications alongside welding and machine tending. Its hollow-arm architecture and stable motion control make it ideal for consistent spray painting operations in automotive and manufacturing environments.
How fast is the cycle time?
SCARA Robot arm take time ranges from 0.365 seconds to 0.42 seconds depending on model, with J1+J2 speeds up to 9100mm/s on the larger units. This is engineered for high-throughput lines where seconds per cycle compound into daily output.
Can the robot be integrated with grippers, vision, or conveyors?
Yes. RL Robotics SCARA Robots systems can be configured with application-specific grippers, feeders, conveyors, sensors, and vision systems to automate a complete workstation, not just the robot arm.
